3 days late

Rhea • Christian🙏🏼X-ray technician☠️Married to the love of my life 10•22•17 ❤💍 Mommy to Grayson Matthew👶🏼💙

So I'm 3 days late for my period but I've had all negative pregnancy tests? When I found out I was pregnant with my son, it was 2 days before my period was about to start. Anyone have this issue? Should I test again in a couple days? I've had minor symptoms. Slightly tender breasts, headache and back pain.
